unix - 如何使用 sendmail 发送带有多个文本附件的 HTML 正文电子邮件

Question

我想发送一个 HTML 文件作为邮件正文，并想在此电子邮件中附加多个文本文件。

由于需要发送 html 文件，因此必须使用 sendmail (我无法使用 mailx 做到这一点)。

如何使用 sendmail 发送 HTML 正文电子邮件和多个文本附件？

BOUNDARY="=== This is the boundary between parts of the message. ==="

{
   echo  "From: $MAILFROM"
   echo  "To: $MAILTO"
   echo  "Subject:" $SUBJECT
   echo  "MIME-Version: 1.0"
   echo  "Content-Type: MULTIPART/MIXED; "
   echo  "    BOUNDARY="\"$BOUNDARY\"
   echo
   echo  "        This message is in MIME format.  But if you can see this,"
   echo  "        you aren't using a MIME aware mail program.  You shouldn't "
   echo  "        have too many problems because this message is entirely in"
   echo  "        ASCII and is designed to be somewhat readable with old "
   echo  "        mail software."
   echo
   echo  "--${BOUNDARY}"
   echo  "Content-Type: TEXT/PLAIN; charset=US-ASCII"
   echo
   echo  "This email comes with multiple attachments."
   echo
   echo
   echo  "--${BOUNDARY}"
   echo  "Content-Type: application/zip; charset=US-ASCII; name="${ZIPFILE}
   echo  "Content-Disposition: attachment;   filename="`basename ${ZIPFILE}`
   echo
   uuencode $ZIPFILE $ZIPFILE
   echo
   echo  "--${BOUNDARY}--"
   echo  "Content-Type: application/pdf; charset=US-ASCII; name="${PDFFILE}
